This command emulates Grep, with its -A and -B options. That's why I
suggested "after" and "before". No other command need to show
context, so it's quite understandable why this one is unique in that
sense.

The problem is that the meaning of the region here says nothing about
the context lines the user wants displayed in the Occur buffer. I
agree that an active region should mean "find matches in that region",
but we still need a way for the user to specify non-default number of
context lines to show with the matches, I think.
